How can I save smartly with my energy assets?

Using your energy smartly doesn't have to be complicated. FlexiO automatically adjusts your consumption to the most cost-effective strategy. The platform takes into account dynamic energy tariffs, peak usage, your solar production, and – if you have one – your electric vehicle. This way, you consume more of your own energy, charge your battery and car intelligently, and avoid unnecessary costs. All you have to do is enjoy the benefits.

How can I save more through grid balancing?

Your energy assets can do more than just power your own home. With FlexiO, you can connect your energy assets to a virtual battery that helps balance the electricity grid. LIFEPOWR provides the technology, and you save even more on your energy bill.

How do I avoid costs during negative injection tariffs?

FlexiO helps you avoid costs during negative injection tariffs by intelligently managing your energy assets.

How does FlexiO impact the lifespan of your home battery?

The biggest mistake you can make with a smart home battery? Not using them for fear of wear and tear. Smart home batteries help you increase self-consumption, save on your energy bills and contribute to a more stable power grid. Yet we often hear the same question: 'Won't my battery wear out faster if I let it be smart?' The answer: no. More than that, by using your battery actively and smartly, you just get more value out of it, all without sacrificing battery life and warranty.

What's the difference between EMS and EMS+?

A traditional EMS focuses on saving energy, often by following fixed schedules and market prices. EMS+ (FlexiO) goes further. It gives you insight into your true energy costs, not just market rates, but also your distribution charges, grid fees and bespoke tariffs. And thanks to self-learning algorithms, it forecasts your behaviour up to 48 hours ahead, adapting to real conditions such as cloud cover or unexpected demand.

What is the difference between Engie Empower Flextime and the ePOWR tariff?

Rates & Billing

engie, empower, flextime, epowr, tariff, dynamic, hybrid, fixed, timezones, flexio, lifepowr, trevion, rates, billing, difference

Engie's Empower Flextime is NOT a dynamic tariff - it's a hybrid contract with fixed time zones instead of changing hourly prices. This tariff is NOT supported by FlexiO. The ePOWR tariff (LIFEPOWR by Trevion) IS a true dynamic tariff with additional benefits: participation in ePOWR AND free FlexiO control (1 year included with every FlexiObox, partners may offer additional free time). With a dynamic tariff + FlexiO you get the best value.

What is the difference between rPOWR and ePOWR?

Grid Balancing

rpowr, epowr, fcr, frequency, reserve, battery, grid, balancing, payout, lifepowr, flexio, energy, trading, tariff, trevion, knights, bill, returns, ebalancing, rbalancing, frequencyregulation, energytrading

FlexiO offers two forms of grid balancing:

rPOWR (FCR - Frequency Containment Reserve)
- Your battery helps stabilize the electricity grid
- You are paid for keeping capacity available
- Payout via LIFEPOWR (3 months delay)
- Available for all FlexiO users with a suitable installation

ePOWR (energy trading)
- Active energy trading on the market
- Requires a compatible ePOWR tariff (e.g., via Trevion or Energy Knights)
- Earnings are directly settled on your energy bill
- Higher potential returns

Tip: With the ePOWR tariff, you combine both forms of grid balancing for maximum returns.

What is the difference between the ePOWR tariff and a regular dynamic contract?

Rates & Billing

epowr, dynamic, tariff, epex, spot, market, flexio, battery, energy, bill, savings, trading, rpowl, monthly, payout, rates, billing

Regular dynamic contract (e.g., Engie Dynamic, Luminus Dynamic):
- Quarterly or hourly prices based on EPEX spot market
- FlexiO optimizes your battery on these prices
- Standard savings on energy bill

ePOWR tariff (available via Trevion, Energy Knights):
- Also dynamic quarterly or hourly prices
- Plus: access to ePOWR (trading energy on the market)
- Combination of rPOWR AND ePOWR possible
